Under acer trees at Jodrell Bank radio telescope observatory a couple of years ago. The place now has an arboretum with many species of trees, and various features including the solar system laid out at distances and sizes in scale to it.
There are new attractions there if you haven’t been there for a few years and if you have been it’s still worth a visit. (You may have to book at the moment).
The radio telescopecitselfvis a massive structure supporting a huge dish. The supports it tips up on come from a ship. It is very impressive.
